Definitions

  • the present invention relates to an accessory for the installation and positioning of lines of importation/exportation, production collection and injection of water and gas in the hull of oil production units, such as SPUs (Stationary Production Units), and FPSOs (Floating Production Storage and Offloading).
  • SPUs Sterary Production Units
  • FPSOs Floating Production Storage and Offloading
  • a pipe assembly For offshore oil production, a pipe assembly is used, which drains the product from a production well in the seabed to a platform, on the surface of the sea.
  • This set of pipes (electro-hydraulic umbilicals, water injection and oil and gas pumping) is traditionally called a production collection line, known in technical terms as a "riser”.
  • This pipe assembly which forms a production collection line, can essentially be subdivided into two separate sections:
  • the production collection line is arranged on the seabed by a specific vessel for this purpose, known as a "PLSV" (Piping Laying Support Vessel).
  • PLSV Pulping Laying Support Vessel
  • the process is started by the coupling of one of the two ends of the piping to the production well, and subsequently, the piping gets released from the production well to the platform for the vessel, which gradually uncoils the piping from its deck as it moves, until it reaches the platform, where it is transferred to the other free end which will have been previously fixed to the platform.
  • This final stage is very laborious, and requires the logistics of various simultaneous and synchronised procedures.
  • the end of the collection line is prepared with its respective fixing/coupling elements and respective processes known in the prior art, which enable the connection to the platform.
  • the first anchoring location is on the level of the lower deck of the platform, or, in technical terms, the "spider deck”.
  • the production collection line as well as the hydraulic and "gas lift” umbilicals must be directed individually, by means of an element known as tube I, or in technical terms "I-Tube".
  • the tube I is fixed on the internal or external flanks of the floats, structures located beneath the water line which support the platform, or in technical terms, the "pontoon".
  • the fuse cables which keep the cap/bend stiffener coupled to the end of the collection line, or in technical terms, the "end fitting" are broken. With the breakage it is possible that the collection line will continue to be moved by traction and will rise inside the tube I up to the level of the lower deck, where it is fixed on its respective support, by means of a bipartite stopper, or in technical terms, a "hang-off', which supports all of the vertical weight of the collection line, whilst the axial loads are supported by the cap/bend stiffener assembly.
  • the weight of the cap/bend stiffener assembly can be up to 10 tons and despite having a stopper in the vertical collection tract approximately 35 metros beneath the operating point, in the event that the connection/mooring of the cap in the dogs of the bell mouth does not effectively occur after the breaking of the fuse cables, the bend stiffener will freely descend via the collection line, its acceleration being extremely violent in this small vertical tract, until it reaches the stopper located just below.
  • Another problem with the logistics of the connection of the free end of the vertical collection tract to the platform is the operational dependence on a whole structure pre-arranged by the weather and sea conditions, such as the rental of ships, the availability of surface crews, equipment, amongst others.
  • the document discloses a device which, in the event that the bend stiffener falls, encourages the opening of vanes, which generate heterodynamic braking.
  • this is an expensive device and structurally complex in terms of manufacture.
  • damping sleeve and anchoring method proposed here were developed from a paradigm shift from the commonly adopted philosophy that is necessary to use a team of divers to carry out the task of manipulating the cables and straps with the aim of executing the connection/mooring of the cap in the dogs of the bell mouth.
  • the disclosure is the result of ongoing research in this pursuit, the focus of which is targeted at the simplification and reduction of costs in operations of anchoring collection lines to platforms. It also aims to create a new anchoring concept with a respective method for application.
  • connection device for connecting a submerged tubular structure to a floating support structure, said connection device comprising a first tubular connection element and a second tubular connection element concentric with said first element, the connection elements being connected respectively to one end of the submerged tubular structure, the first tubular connection element being provided firstly with a first shoulder serving to co-operate with a corresponding first abutment face of the second tubular connection element to form a first axial abutment in a pulling direction in which the submerged tubular structure is pulled, and secondly with a second shoulder serving to co-operate with a corresponding second abutment face of the second tubular connection element to form a second axial abutment in a direction opposite from the pulling direction; locking and tensioning means being mounted between the first and second tubular connection elements to act, by putting the first and second shoulders simultaneously in contact with the first and second abutment faces, to provide coupling with zero axial clearance between the two connection elements.
  • US 5,947,642 discloses an apparatus and to a method for facilitating the connection of underwater flexible risers coming from the sea bed at any point located above the sea surface on a surface structure.
  • Two principal components are used, namely a guide device, and a connection device, which is connected to an underwater flexible riser which it is desired to connect to the structure.
  • the connection device comprises a bending stiffener with a guide provided on the upper end thereof.
  • the present invention provides a damping sleeve according to claim 1.
  • the invention relates to an anchoring method according to claim 10.
  • damping sleeve and the anchoring method of the disclosure were developed from research which was intended to find a concept which eliminated the need to use fuse cables and safety straps, as well as the presence and intervention of a team of divers.
  • the bell mouth (6) regardless of the sequence chosen for the task, some stages are indispensable, and within them the task of fixing the safety straps (2) between the bend stiffener (4), or cap (5) and the bell mouth (6) carried out by divers, can be cited as a form of preventing the fall of said assembly in the event that said cap (5) is not connected/moored in the dogs around the bell mouth (6) [not depicted], after the breaking of the fuse cables (1).
  • Figure 2 depicts a schematic side-view image wherein the damping sleeve (100), object of the invention, is arranged in the initial position of the anchoring process of the collection line (3) directly encased in said collection line and in the lower part of the bend stiffener (4).
  • the damping sleeve (100) essentially comprises a bipartite structure with a cylindrical shape, fitted with a central opening or core (101), which extends coaxially from one end to the other of said structure.
  • the core (101) has a substantially cylindrical shape with a diameter equal to or greater than the external diameter of the collection line (3).
  • the damping sleeve (100) is coupled on the free end of the collection line (3), when it is still on the PLSV vessel, being installed on the lower part of the bend stiffener (4).
  • the coupling is carried out manually by means of screws or any other fixing means, such as a clamp, and eliminates the use of fuse cables connected between the cap (5) and the end fitting/connector (7').
  • the damping sleeve (100) comprises specific tracts, namely: a main body (110) and a lower tract in the form of a ring (130).
  • the main body (110) comprises an upper part (111) and an intermediary part (112), both of metallic material capable of supporting all of the various forces to which the damping sleeve (100) will be subjected.
  • the upper section (111) has the core (101) with a conical shape equivalent to that of the lower external end of the bend stiffener (4), in which it is directly encased.
  • the intermediary part (112) is provided with a cavity (112') along the entire internal circumference of the core (101). Said cavity (112'), in turn, is provided with a compression plug (120), formed from polymeric material, firmly fitted to the collection line (3).
  • the compression plug (120) can be formed by two contiguous sections of polymeric materials and both with different properties, each one is programmed and fitted so as to resist specifically limited tensions.
  • the damping sleeve (100) is also provided with a final lower tract, formed by a damping ring (130), fixed directly on the lower end of the intermediary part (112).
  • the damping ring (130) follows the shape of the main body (110) of the damping sleeve (100) and has a length equivalent to at least 1/3 of the total length of said damping sleeve (100).
  • the damping ring (130) is made from polymeric material and is capable of damping a potential blow between the bend stiffener (4) / cap (5) assembly and a stopper (9) located in the collection line (3) at approximately 35 metres below the bend stiffener (4).
  • the upper part (111) of the main body (110) is further provided with four lugs (140), distributed equally along its external edge.
  • the lugs (140) are made available for a potential need in the total execution of the activation of all of the dogs of the bell mouth (6).
  • one of the dogs of the bell mouth (6) may not be activated.
  • said lugs (140) are used as a support point so that the cables stop moving the cap (5) by traction, executing the anchoring, and the PLSV vessel, with its high rental costs, can be eradicated.
  • the disclosure also comprised an anchoring method, much simpler and not dependent on the operations of teams of divers, and consequently, not subject to the influence of sea conditions.
  • the initiation of the processes for carrying out the anchoring of the collection line (3) on oil platforms includes the following stages:
  • the damping sleeve (100) will maintain the assembly in position, as well as enabling this assembly to descend in a gentle and controlled manner until it reaches the stopper (9), thereby preventing any damage to the bend stiffener (3) and flexible duct.
  • the damping ring (130) will also be capable or protecting the bend stiffener (4) from any damaging impact.
  • the cables/safety straps (2) are dispensable. It will therefore be possible to carry out the connection of up to one complete assembly (bundle), without the accompaniment or direct assistance of a diver, releasing the PLSV vessel.
  • This method enables a fast, efficient connection which is not dependent on sea conditions, making the calculation of the total costs of a package more predictable, and the whole operation more stable.
